【正确答案】 C

【答案解析】解析：本句考查call动词短语的用法。call for，要求，需求，如：This invitation does not call for an answer(这张请帖不要求答复)。因此C最符合题意。call off，取消，如：“The football match was called off on account of rain(足球赛因下雨取消)。call up，打电话，如：“I’ll call you up as soon as I get home(我一到家就给你打电话)。call at，拜访，如：We called at John’s house yesterday(昨天我们到约翰家拜访)。
